Nursing research: Methods and critical appraisal for evidence-based practice (7th ed.). Thus to accurately measure a phenomenon, the measurement tool(s) must be based on a reality and be as objective as possible. Qualitative Research Quantitative Research Objective/Purpose To gain an understanding of underlying reasons and motivations To uncover prevalent trends in thoughts and opinions To quantify data and generalize results from a sample to the population of interest Sometimes followed by qualitative research to explore findings further This includes describing sampling processes, sample size, and data-gathering instruments such as questionnaires, interviews, observation, and technical measuring devices used in physical sciences.

(2012) Nursing Research: Generating and Assessing Evidence for Nursing Practice (9th ed.) What Is the Purpose of Quantitative Research Proposal? Qualitative data is descriptive data that is not expressed numerically. Thus the objects of interest are measured by instruments (e. G. , telescope), the data is examined and analyzed to determine if logical patterns are present, and rational theories are constructed to explain and predict a variety of facts (Hathaway, 1995).

Ontologically the researcher assumes that the external reality is comprised of facts that are law-like and provide structure or a theoretical framework to this reality. Statistics can be used to formally test hypotheses or predictions. Methodological assumptions(research strategies): Using quantitative research methods such as experiments, quasi-experiments, exploratory and analytical models, case studies, and so onwhich require objective measurement and analysisis the only acceptable method to generate valid knowledge. 4 0 obj Based on the sampling method used, the results may be generalized to a larger population.
